ADS fuse 2000 Cherokee

My brother's 2000 Cherokee keeps blowing the ADS fuse under the hood.

Does anyone know what this is, where it runs, and if there are any common problems in relation to this.

Any help would be greatly appreciated. Even if you can jsut kind of point me in a direction to start looking! Thanks!

Do you mean the ABS fuse? ABS stands for Anti Lock Braking system.

If it is the ABS...you need to be more specific...
Does the fuse blow immediately or sporadically?

I personally have not seen it, but my brother insists it is ADS. He said his owners manual makes no mention of it.
The fuse blows periodically. Every couple of days it burns out. The fuse is under the hood. When it blows it kills the engine. He says everything else works, just the engine wont run.

Are you sure it's not the Automatic Shut down fuse it shuts engine down completely. Could be bad ASD relay or short somewhere in system. Dale
[email protected] Yes, Chrysler calls it a ASD--Auto Shutdown Relay It is located in power distribution box pass. side under hood

Does Chrysler call it that? ADS relay? My diagram of the Power Distribution Center call for an Auto Shutdown, but shouldn't that be an ASD relay? Just checking because the dealer folks sometimes use a different name than the folks on the forum.

I know that DC-XJ parts book and the folks here use the term NSS for what the Chrysler techs call the "prindle" switch (for PRNDL).

Hey Fantastic...

This diagram might help you, it will be available for your use and will be removed shortly after.

It appears that maybe the downstream O2 sensor could be shorted (melted wire or cut wire).
Or the ignition circuit.

Wow, thanks for the diagram! That will likely help a lot. When I asked if he was sure it wasnt "ASD" instead of "ADS" he went back and checked and sure enough you guys are correct, it is "ASD"

Saturday we are going to get together and check the O2 sensors.

I am guessing I can just unplug them both and throw a new fuse in and see if it blows it?

I'll also check as much of the wiring as I can follow before doing that.

Is there anything else you guys would recomend in the diagnosis?

I appreciate all the help!

Glad you got the diagram...let me know if you need me to look up anything else.

I cannot leave diagrams posted on the web (copyright issues, etc..)..ok for your personal use.

In my experience with automotive repair,,,.....i have found that wires get burned on exhaust pipes and sometimes get cut on sharp body parts. That is why it is important to tie wrap everything down so they don't rub or burn.
